Design of Langmuir Probe Sweep Voltage Source for CN-H1 Stellarator

The CN-H1 stellarator device features advantages including flexible design with adjustable magnetic field configurations and advanced diagnostic systems. Accurate plasma parameter information is crucial for conducting related research on the CN-H1 stellarator, where critical parameters such as plasma space potential and floating potential fundamentally rely on Langmuir single probe scanning. This study developed a scanning voltage source for Langmuir probes, utilizing Multisim software as the simulation platform to conduct circuit simulations of the designed voltage source for verification. The research results demonstrate that the design of the probe scanning voltage source exhibits rationality and feasibility.
